Answer: You might have messed up the question

Here is the answer based on your question

W (Bottled water) = 7/2$

N (Cheese Nachos) = -1/2$

Step-by-step explanation:

2W + 3N = $5.50

3W + 2N = $9.50

Find the common number and subtract them. In order to find isolate the water bottles or nachos. I will do water bottles

15 (2W + 3N = $5.50)

10 (3W + 2N = $9.50)

30w + 45N = $82.5

Minus

30W + 20N = $90

= 25N = -12.5

N = -1/2$

Substitute for N

3W + 2(-1/2) =9.5

3w -1 = 9.5

3w - 10.5

w = 7/2$

After leaving the runway, a plane's angle of ascent is 15 degrees and its speed is 272 feet per second. How many minutes will it
Mice21 [21]
<h2>It takes 3.31 minutes the airplane to climb to a height of 14,000 feet</h2>

Step-by-step explanation:

Angle with horizontal = 15°

Velocity of plane = 272 feet per second angle of ascent is 15 degrees

Velocity of plane = 272 cos 15 i + 272 sin 15 j = 262.73 i + 70.40 j ft/s

Vertical velocity = 70.40 ft/s

Vertical displacement = 14000 ft

We have

      Vertical displacement = Vertical velocity x Time

      14000 = 70.40 x Time

      Time = 198.87 seconds = 3.31 minutes

It takes 3.31 minutes the airplane to climb to a height of 14,000 feet

Write an expression for how many boxes Jack has now

A. 1/2b+4

B. 1/2+4b

C. 4b−1/2b

D. b+42/2

Answer:

C. 4b−1/2b

Step-by-step explanation:

Let the number of boxes that Jack has be represented by b

In the question, we are told that:

• On Tuesday, Jack bought 4 boxes

Since 1 box = b

4 boxes = 4b

• On Wednesday , half of the boxes where destroyed.

= 1/2 b

The expression for how many boxes Jack has now is given as

Number of boxes Jack bought in Tuesday - half of the boxes destroyers on Wednesday.

This is expressed mathematically as:

4b - 1/2b
